This LO only has a couple teeth but YDS had all 4 one year molars at his 9 month visit. The ped said it's on the very early side but not unheard of. He also had 8 teeth at 5.5 months so he was clearly an early teether. Our ped dentist said the same. Statistically speaking kids that teeth early begin losing teeth on the early side (around age 5) that's definitely been the case for YDS. Definitely mention it to your dentist or ped if you're concerned.
